Battery Cycle's vs. Discharge

BAE Cycle Life

The systems may require some power from generator during winter and the other odd day here and there. Other times there will be typically be a surplus of solar power during the day that could be used for irrigation, pool pumps, home heating/cooling, water heating etc.

Home heating should primarily be with wood or LPG, although using reverse cycle AC for short periods is typically ok.

Please speak to me about your water heating requirements before purchasing a “solar hot water system” as there is typically surplus electricity that can be used to assist.

If you are thinking of a heat pump hot water system I highly recommend the Sanden units. They use 1kw when running, work well at low ambient temperatures and are very very quiet compared to other units.
